Various observational data sources are currently available for weather forecasts. Besides atmospheric remote sensing data from satellites and ground instruments, surface data is measured at ground stations. However, a crucial layer, the so-called Planetary Boundary Layer (<2km above ground), is only sporadically covered by radio soundings. For this reason, existing weather models fail to predict weather phenomena such as fog, high fog and thunderstorms properly which is why Meteomatics has made it its mission to close this data gap. For this purpose, a flying weather station, the Meteodrone, was developed by Meteomatics. Each Meteodrone is currently being controlled by one drone pilot, which is not suitable for an increasing number of flight locations. With the development of the MeteoBase, one pilot is able to simultaneously operate more than one aircraft for the first time in the history of aviation. For example, using the MeteoBase, an operator is able to control 10 drones at the same time. What exactly the MeteoBase is and how it revolutionizes the field of weather prediction, is described by SRF Einstein in an exciting contribution to the topic "Weather - calculate the unpredictable".
